Abstract

A multi-level memory array is described employing rail-stacks. The rail-stacks include conductor (40) and semiconductor layers (38, 39 and 41). The layers are generally separated by an insulating layer used to form antifuses (42). In one embodiment, one-half the diode is located in one rail-stack and the other half in the other rail-stack. Methods for fabricating a multi-level memory array are also provided.
